The games are for fixed numbers of participants (Most are for exactly four, a few are for three, and a few are for 5-6). No GM is needed, although one participant needs to lightly facilitate by organizing play and keeping track of time.
The book also includes a chapter on designing your own games in this format, with a worked example: The Race!
Did we mention that you can play an entire game, complete with blood, betrayal, and heartbreak, in an hour? You can! Nine of them, in fact. That’s a lot of Hours!
